It all boils down to remote device management. Verizon require its phones to be available for remote access, for provisioning and other services. Apparently Windows Phone 8 devices don’t meet that requirement so Verizon are hesitant in using the devices in their current state.

In rare cases, if remote access is not granted, the devices can stop responding to certain systems on the carrier’s network. It has been suggested Microsoft and Verizon are in talks to resolve the situation, however Microsoft have been said to be unwilling to give any waivers on this issue. There has been no word on what these waivers would include.
